Geological lineaments are linear or curvilinear surfaces that are considered a superficial expression of discontinuities on the earth’s surface. The extraction of lineaments from remotely sensed satellite data is one of the most frequently used applications of remote sensing in geology. This study focuses on the semi-automatic extraction of lineaments in the Girón–Santa Isabel basin using a Topographic Position Index (TPI). The lineaments were extracted in the PCI Geomatics 2016 software and analyzed in the ArcGIS and Rockworks software. Statistical and density map analyses of the lineaments were performed; then, these results were interpreted to obtain the geological lineaments. Finally, a bibliographic verification was carried out, and structures such as faults and folds were defined. The total number of geological lineaments was 76, and 71 of them were defined as faults, the longest with a length of 33 km. It was determined that the preferential orientation of the lineaments is NE–SW, which is consistent with the axis of the Girón–Santa Isabel basin. This methodology can be useful to optimize time and reduce costs when gathering the structural information of the study area in the first stage of geological and mining prospecting or the educational field.

Abstract-This project was developed within the framework of relationship with the Community, where university students carried out internships under the servicelearning methodology. Resumen.-Este proyecto se desarrolla dentro del marco de vinculación con la sociedad, mediante el cual los estudiantes realizan prácticas pre profesionales bajo la metodología de aprendizaje de servicio. El propósito del proyecto es brindar asesoramiento técnico a Pequeños Mineros y Mineros Artesanales del Distrito Minero Ponce Enríquez -Ecuador, solventando las carencias detectadas en el aspecto técnico de la actividad minera, y a la vez acercando a los estudiantes a la realidad social con una postura proactiva y participativa de servicio a la comunidad.Palabras-clave: vinculación con la sociedad, prácticas preprofesionales, minería, desarrollo productivo.Abstract-This project was developed within the framework of relationship with the Community, where university students carried out internships under the service-learning methodology. The objective of the project was to provide technical support to Small Scale Miners and Traditional Miners at the Mining District of Ponce Enriquez -Ecuador, for solving technical gaps detected in the mining activity. Thus, this project contributed to provide information to university students about the social reality of the rural areas of Ecuador, contributing to the creation of a proactive and participative position of the students for helping the community.
